Abstract :
The effect of body movement on performance of body area communication system was studied. Channel gains on body standing, walking, and running were measured in experiments. Based on the experiments´ data, channel gain obeyed normal distribution. Parameters were estimated using maximum likelihood method. Then, channel statistical and simulation model has been established to analyze the system performance. The general methods of body area communication channel modeling and simulation were given. Results show that BER increased slightly with fierce degree of body movement.
